Fletching
From Ultima Online Forever Wiki
Bowcraft (or Fletching as it is called) is a skill where a player uses Fletching Tools to create arrows, bolts, bows, and crossbows.
Crafting in the Britain Crafting Area will also have a chance to create "slayer" weapons. See the Slayer wiki for more details.
Only Skill Scrolls are available for this skill.
How to Train
Training Method
0 - 40 Train at Britain NPC Bowyer
40 - 60 Craft bows
60 - 70 Craft Cross Bows, can also do regular bows but it was tested to be quicker with Heavy'sXbows.
70 - GM craft Heavy.
In a previous edit it seems the method was 40-60, 60-gm with heavy xbows. However, you can no longer crafter xbows under lvl 70.
